John Logie Baird was born in Helensburgh and was the first person to build a working television. By 1924 he'd managed to transmit a flickering image a few feet and in 1926 he gave a demonstration before 50 scientists in London.
We have John Reith to thank for the very concept of broadcasting as a way of educating the masses. He established the tradition of independent public service broadcasting and was one of the BBC's first founders.
An invention that has saved thousands of lives, penicillin was discovered by Sir Alexander Fleming in 1928, a scientist born in Darvel, East Ayrshire.
Scots Frank Barnwell and his brother Harold built a total of three aircraft in the years 1908-10. Frank laid out some principals of aircraft design in a paper which then became fundamental to all future aircraft design.
It probably comes as no surprise that golf was invented in Scotland. Records of the game have been found from as early as the Middle Ages, with the first written rules and invention of the 18 hole course dating form this period.
A Scottish engineer from Helensburgh - Henry Bell - was the man responsible for introducing the first successful passenger steamboat service in Europe, which took place in 1812.

Edinburgh-born Alan MacMasters invented the very first electric toaster in the 1880s. It was brought to the mass market as the 'Eclipse' but unfortunately became the first fatal cause of an appliance fire in Britain.
Another Edinburgh man, Alexander Cummings was the inventor of the not-so-glamorous but certainly essential flushing toilet in 1775.
In 1755, William Cumming created a small artificial refrigeration machine which he demonstrated to his university students. The idea had no practical applications at the time but later evolved into the modern fridge.
Next time you take soup out for lunch in a flask, think of Sir James Dewar, who came up with the vacuum flask in 1892 as a result of his research in the field of cryogenics.
